After hearing the news that NASA had "emailed" a wrench up to an astronaut on the ISS through its 3D printer, there was one word that kept coming up: Replicator. So, do we finally have a working replicator on our hands?

If a tiny workshop has prevented you from adding one of MakerBot's Replicator 3D printers to your toolkit, today is your lucky day. The company has announced a smaller version of its Replicator 3D printer—aptly called the Replicator Mini—with a smaller footprint, easy one-touch printing, and even a networked camera…

MakerBot is building an empire selling printers that make things—but have you ever wondered where the printers themselves are made? On June 7th, the company opened a huge new factory to accommodate the booming demand for Replicators, and we got a first-hand look inside.

Somewhere deep in the Marshall Space Center, in an unmarked beige hangar, NASA is building a spaceship. A spaceship built with spare parts, scrap hardware from the International Space Stations, a left-over aluminum-lithium cylinder and even museum mockups. One day, it may become the vessel that takes humans to Mars.

We told you about MakerBot's new 3D printer when they announced it. We showed you a hands-on video of how it cranks out beautiful plasticky toys. But what we haven't shown you, until now? What's inside the spaceship.

Researchers at the Russian Academy of Sciences are developing a technology that could lead to a real-life Star Trek replicator. They have demonstrated that it is possible to manufacture an array of identical atomic nanostructures in controlled shapes and sizes.

A spaceship or a gigantic death ray is cool, but wouldn't you rather have an awesome scifi gadget you could slip into your pocket or clip to your belt for easy access? When you're on the interstellar warpath, you want the very best, so we've put together a list of some science fiction mobile devices that will make…
